Olav Martin Kvern ĕ207 Phinney Avenue North Seattle Washingtonę8103 We could easily change the structure to change the way that the name information is stored, for example. Each element, in turn, can contain other elements. Here, the “author” XML element contains the other elements. Olav Martin Kvernĕ207 Phinney Avenue North Seattle Washingtonę8103 XML elements may contain other elements, as shown in the following example. The title just shown is an example of an XML element (containing the data “Revolutionary Girl Utena”). XML elements are the fundamental building blocks of an XML file. Something like this: Revolutionary Girl Utena XML Element. XML must be “well formed,” which means that any “start” tag must be matched by an “end” tag. Tags are marked with angle brackets (also known as greater than and less than symbols), like “”. Tag.Ī tag is a label for a piece of XML data a tag is not an XML element. When we talk about XML, we’ll be using a standard set of terms, for which we offer the following non-standard set of definitions. Working with XML outside InDesign, one becomes accustomed to certain things: finding a given element by its content using XPath, for example, or being able to use the content of a given XML element in multiple places in a web page generated from the XML You can’t do those things in InDesign-at least not directly. If you’re familiar with XML, this can be a major conceptual stumbling block. It gets turned into an InDesign representation of the XML structure. When you import XML into an InDesign document, it isn’t XML anymore. In short, XML is as simple or complicated as you care to make it. You can easily end up paralyzed by the sheer number of possibilities-there are a limitless number of ways to accomplish a given task. Indeed, the biggest problem of implementing an XML publishing workflow is figuring out the design of the XML data structures you want to work with. While we said that XML is simple (as opposed to complex), we never said that it couldn’t be complicated. The formatting of XML data-if that data ever appears in a document-is up to you. HTML is about what things look like XML is about what elements are. This isn’t the case-the two markup schemes are different in kind. It would be easy to fall into the trap of thinking that XML is something like an expanded version of HTML. You’re not limited to, ,, and so on, as you are in HTML. That’s what the “extensible” part of the acronym means. Unlike HTML, XML doesn’t have a limited set of predefined tags. Like HTML, XML uses tags, such as “” to mark a piece of text.
Any application that can write text files can be used to write XML. XML is a way to mark up (or tag) information in a text file. With all of the buzzwords and jargon surrounding the topic, it’s easy to lose track of something very basic: XML is simple.
XML stands for “Extensible Markup Language.” What the heck does that mean? It’s easy to be scared off-XML is usually mentioned in the same breath as SOAP, DTDs, metadata, structured content, and schema.
